How long did you have her in his tank (while she was in her own jar/vase) prior to letting her out to be with him? Stripes doesn't mean she is ready to mate.. mine stripes up every time there is a male close, but they are in no way ready to mate.
Which makes me ask.. which line are you talking about? A line from head to tail, or the bars up and down the body from top fin to lower?
Here is some info you need to consider before take on this long, expensive, hard journey.. make sure you have everything needed.. conditioning the fish, all the spare tanks, jars, heaters, etc you will need for the fry - plus cultivating the food..
- definitely need to do a lot of research and even though there is a lot of info in these links, there is still so much more when breeding.
Conditioning & spawning
Raising the fry
And last but not least: Feeding the fry
Just be prepared for hundreds of fry, where you are selling them to, how you are going to house each male prior to selling them so that they are healthy, culling the babies if needed, etc.
Since you sound unsure and just willing to go with any male, I honestly don't think you've done all the research needed and understand just how overwhelming and expensive this can become.
